Purpose
The purpose of this study was to characterize social communication and structural language of school-age girls with high-functioning autism spectrum disorder (HF-ASD) compared to a matched group of girls who are typically developing (TD).
Method
Participants were 37 girls between 7;5 and 15;2 (years;months)—18 HF-ASD and 19 TD. Children completed the Test of Pragmatic Language–Second Edition (TOPL-2) and Clinical Evaluation of Language Fundamentals–Fifth Edition. Parents completed the Children's Communication Checklist–2 United States Edition (CCC-2) and Receptive and Expressive Communication subdomains of the Vineland Adaptive Behavior Scales–Second Edition.
Results
In the area of social communication, girls with HF-ASD earned significantly lower scores and were more often classified as having an impairment on the TOPL-2 and the CCC-2. However, 28% and 33% earned average scores on the TOPL-2 and the CCC-2, respectively. In the area of structural language, no significant differences were found between groups on Clinical Evaluation of Language Fundamentals–Fifth Edition indexes. In contrast, girls with HF-ASD earned significantly lower scores and were more often classified as having an impairment on the Vineland Adaptive Behavior Scales–Second Edition. Sixty-one percent and 83% scored below average on the Receptive and Expressive Communication subdomains, respectively.
Conclusions
It has been argued that girls with HF-ASD, when compared to boys with HF-ASD, may have advantages for social communication and structural language that mask their impairments. However, when compared to girls who are TD, girls with HF-ASD demonstrated impaired social communication and structural language. Clinicians should include and carefully examine multiple sources of information when assessing girls with HF-ASD.
